What is a Joint and classification of joints

Functional Classification

based on range of motion of the joint

Structural classification of joints

based on the material that binds the bones together and the presence or absence of a joint cavity -fibrous joints -cartilaginous joints -synovial joints

cartilaginous joints

cartilage connects

Fibrous joint

collagen fibers connect

Symphyses (Cartilaginous Joint)

fibrocartilage

Diarthroses

freely movable joints predominate in Appendicular skeleton

Synchondroses (cartilaginous)

hyaline cartilage units bones (epiphyseal)

Synarthroses (functional)

immovable joints largely restricted to Axial Skeleton

Syndesmosis (fibrous joint)

ligaments (tibiofibular and readioulnar)

Sutures (fibrous joint)

minimal tissue (skull)

Gomphoses (fibrous joint)

peg in socket (tooth)

Articulation

rigid elements of skeleton meet at joints enables resistance to crushing tearing and other forces

Amphiarthroses

slightly movable joints largely restricted to Axial skeleton
